OptiScaler Client, a management tool for enabling upscaling and frame generation technologies in games, has been released in version 1.0.7.
The tool swaps in DLLs like FSR 4, DLSS or frame generation modules on a per-game basis, without needing a manual OptiScaler install.
New in this release is comprehensive FSR 4 DLL swapping with INT8 and FP8 support, plus direct Frame Generation and Multi Frame Generation with multipliers of up to x6.
What’s Changed
